[tlbuild] tl10 rebuild

[Karl Berry]

Ok, let's now do one more, hopefully final, rebuild.

I updated asymptote to 2.00 (minor changes only from 1.99), so for those
who build that, please update that too.

I'll check in i386-linux and sparc-linux in a bit.

My goal is to freeze all normal updates around July 16, make only critical
bug fixes after that, and deliver the final release images to Manfred
around July 22.

Thanks,
k
